Definitions

  • the patent application relates to a propulsion agent for. Aircraft or ships
  • the invention aims to remedy this situation.
  • the invention as characterized, allows on the one hand the possibility to almost completely avoid the swirl losses, but also to use types of thrust generation by other forces besides the momentum effect.
  • FIG. 1 shows the structure of a ship propeller according to the invention.
  • an impeller (1) having a blading (3) and a blade (6) rotating with the blading is rotated about with a drive shaft (4) through a ship-fixed front displacer (2).
  • the inflowing water into the inlet of the blading (3) is directed by this displacement body around which the water flowing in the blading in an inlet.
  • the water flows around a streamline body (5) from the ship.
  • 1b shows the principle of the development of the blade profiles.
  • the blades move in the direction of the peripheral speed u.
  • the flow enters at the inlet velocity v in in the region a in the blade grid with a small inlet surface.
  • region b the flow area is increased by changing the blade pitch, thus reducing the fluid velocity and increasing the pressure.
  • area c the fluid is accelerated again and the pressure is lowered to the ambient pressure
  • FIG. 2 shows the propeller according to the invention with casing (6) in FIG. 2a and the blade forms without casing in FIG. 2a.
  • FIG. 3 shows a ship propeller or engine fan according to the invention in FIG. 3a and a lifting propeller in FIG. 3b
  • Fig. 4 shows the use of additional forces on the jacket.
  • the centrifugal force (F) is shown perpendicularly away from the propeller shaft to the outside on the inside of the shell.
  • the vector of normal force (N) against the engine mantle is inclined to the vector of centrifugal force, so that the fluid is accelerated obliquely away from the impeller axis.
  • the counterforce generates a thrust force (S) on the impeller shell. It can be shown that this thrust on the impeller shell can be very high (about 20% of the centrifugal force).
  • control devices (21, 51) are shown in order to change the outflow velocity and / or the outflow direction.
  • Fig. 8 shows the lifting forces on a ring wing for a lifting screw.
  • FIGS. 9 and 10 show a narrow, rotating annular wing (30) with a blading (32) over a stationary annular body (31).
  • Figure 1 1 is a propeller (40) with shell (41) and drive shaft (42) in front of a displacement body (43) with channels (44) which generate a negative pressure at the back of the displacement body, so that the flow applies well and so a detachment is avoided.

Abstract

L'invention concerne un moyen de propulsion ou une hélice pour des aéronefs ou des navires. Le rayon de la ligne médiane de sortie M2 de l'hélice est augmenté par rapport à celui de la ligne médiane d'entrée M1 de sorte que les pertes de tourbillons sont réduites et la surface extérieure (6) est utilisée en tant que surface supplémentaire qui produit une poussée supplémentaire par rapport à une hélice classique dans le sens de la marche pour une masse de passage donnée à travers l'hélice.
